3.     Have the following section assessment questions answered using a complete sentence in your ring binder:

Group 1: Viruses

1. Give several reasons why viruses are not considered living organisms.

2. What are the steps in the lytic cycle of a virus?

3. Compare and contrast the lysogenic cycle and the lytic cycle.

4. Why are viruses that go through lysogenic cycle particularly dangerous to humans?

Prokaryotes, Eukaryotes, and Viruses Tutorial

    The goal of this exercise is to introduce you to the kinds of cells that make up all living systems, and to contrast cells with viruses. You should be able to name the 6 Kingdoms, understand the differences between prokaryotes and eukaryotes, and be able to describe the basic functions of the eukaryotic cell organelles.
